Product Introduction

Overview

The ADAU1372BCPZ is a low-power codec designed by Analog Devices Inc. This component is optimized for low latency and low power consumption, making it ideal for use in headsets, handsets, and headphones. The ADAU1372 incorporates four single-ended analog inputs, configurable as microphone or line inputs, and two outputs. It also features built-in programmable gain amplifiers (PGAs), asynchronous sample rate converters (ASRCs), and supports serial port sample rates from 8 kHz to 192 kHz. With its versatile control interfaces, including I2C and SPI, the ADAU1372 provides a comprehensive solution for various audio applications with minimal external components.
